IMPROVEMENT IN PLows.

Specitication forming part of Letters Patent 151097,74@ dated December7, 1869.

To all 'who/Jn it 'may Concern.-

Be it known that I, ALEXANDER WRIGHT, ofthe city and countyY ot'Allegheny, and State of Pennsylvania, have invented certain new anduseful Improvements in Plows; and 1 do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and tothe letters Of-reference markedthereon.

The nature of'my invention consists in providing a reversible mold boardot' a plow with two lugs, one lug near each plowshare-point, for `thepurpose of strength and stiffness to the mold-board, and forming a po'ntof attachment for the point of the landside.

To enable others skilled in the art to make and use"my invention7 I willproceed to describe its construction and operation.

In the accompanying drawings, which form part ot' my speci tication,Figure l is a perspective view of my improvement in plows. Fig. 2

N is a' side elevation ot' the same. Fig. Sis a back end view ot' thesame.v i.

The several parts ot' my improvement in plows may be made of cast-iron,wrought-iron, or steel, and thebeam and handles may be made of wood oriron, and of any ofthe known forms suitable forplowsot' the formrepresented in theaccompanying drawings, in which- A represents themold-board, which is pro-v vided with two plowshare-points, e andf,which are so" arranged with relation to the outline and curvature ofthe moldfA that it can be reversed on its bed or standard B,so as tobring either thepoint e or f in to operation. The

mold-board A is provided with two parts, S, y which project backwardfrom the face pf the mold-board, as shown in' Figs. 2 and 3. Theshoulder as ot' the part S is fitted to the shoulder x of,l the landsidcy. The part marked C of the standard B is used as a bed for the back ofthe mold-board A, and the mold-board is held in position on the bed G bymeans of the bolts l and 3. The opening 4 inpart S ofthe mold-board A isused for the bolt 3, which is for securing this part of the mold-boardto the lower part ofthe standard B.

To the standard B is secured, by means of a bolt, 2, a cutter, D, thelower end of which is tted into a recess made inthe points e and f.

lhe openings 5 and 6 in the top of the standard B are used for thepurpose of securing it to the beam of the plow.

The mold-board A may beV so turned or reversed as to bring the point einto operation,

which will cause the pointf to occupy the position ot the pointe, asshown in the accompanying drawings, by simply removing the bolts 1 and3, and then again securing the. mold-board in the desired position bythesamebolts.

The advantage of constructing a plow as herein described will beapparent to manufacl turers of plows and to farmers.

Having thus described my invention, what I claim as new is- Providingthe mold-board A with lugs S and combining it with the cutter D,substantially as hereu described.
